SERVICING NOTES

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK OR BASE UNIT

The laser diode in the optical pick-up block may suffer electro- static break-down because of the potential difference generated by the charged electrostatic load, etc. on clothing and the human body.

During repair, pay attention to electrostatic break-down and also use the procedure in the printed matter which is included in the repair parts.

The flexible board is easily damaged and should be handled with care.

NOTES ON LASER DIODE EMISSION CHECK

Never look into the laser diode emission from right above when checking it for adjustment. It is feared that you will lose your sight.

NOTES ON HANDLING THE OPTICAL PICK-UP BLOCK (LCX-5R)

The laser diode in the optical pick-up block may suffer electro- static break-down easily. When handling it, perform soldering bridge to the laser-tap on the flexible board. Also perform mea- sures against electrostatic break-down sufficiently before the op- eration. The flexible board is easily damaged and should be handled with care. (See Fig.1)

•In performing the repair with the power supplied to the set, re- moving the MAIN board causes the set to be disabled.

In such a case, fix a convex part of the open/close detect switch (S806 on MAIN board) with a tape in advance.

Handle the FLEXIBLE board (overwrite head) with care, as it has been soldered directly to the MAIN board.

In repairing the component side of MAIN board, connect the FLEXIBLE board (overwrite head) and the MAIN board with the lead wires in advance. (See Fig.2)

•The shipment data will be cleared when the NV is reset. There- fore, change the NV adjusted values following the Change of NV Adjusted Values immediately after the NV was reset. (See page 20)

•This set requires the patch data in the nonvolatile memory (IC804) to be rewritten using the application, when the MAIN board or nonvolatile memory (IC804) was replaced. (See page 30)

The MZ-S1 was particularly popular for its ability to record audio in a compact format, making it an attractive option for those who desired high-quality sound in a portable package.

One of the defining characteristics of the MZ-S1 is its use of MiniDisc technology, which allowed users to record and store audio with impressive sound quality. It leveraged Sony’s ATRAC (Adaptive Transform Acoustic Coding) compression, ensuring that recordings maintained clarity while efficiently utilizing disk space. The MZ-S1 supported various recording modes, including SP (Standard Play) and LP (Long Play), providing flexibility in terms of sound quality and recording duration. This capability made the MZ-S1 an ideal choice for musicians looking to record rehearsals, as well as for consumers wanting to create custom playlists.

The MZ-S1 features a sleek, compact design that embodies the portability and aesthetics of early 2000s electronics. Its user-friendly interface is complemented by an LCD display that provides essential information such as track numbers, remaining recording time, and battery life. Additionally, the MZ-S1 was equipped with various connectivity options, including a line-in for direct recording from external sources and a headphone jack with volume control for private listening.

Powering the device was a rechargeable battery, which allowed for extended use without the need for constant replacements. The MZ-S1 also featured a durable construction, appealing to users who needed a reliable audio recorder for travel or outdoor use. This model proved particularly popular among students, journalists, and music enthusiasts, as its compact size and high-quality output made it an indispensable tool for capturing audio on the go.

Moreover, the MZ-S1 allowed users to edit tracks directly on the device, facilitating seamless transitions between recordings. With its blend of innovative features, robust technology, and portable design, the Sony MZ-S1 remains a noteworthy piece of audio equipment, encapsulating an era of digital audio evolution that paved the way for modern music consumption.
